PowerVR Tomb Raider Zip Files      Version 1.06
===============================================
This PowerVR version of Tomb Raider has executables for both the 
PCX1 and PCX2 chips. 

Version 1.06, 25 July 1997.
This now works with Cyrix CPUs, and fixes problems with 800x600 modes
on Matrox graphics cards.

Depending on your 2D graphics card it can allow you to run at 
various resolutions including 640x480, 800x600 and 1024x768. 
Even if your 2D graphics board has only 2MB, you may still be 
able to run at 1024x768 in Single Buffered mode. Linear MIP 
mapping is supported and on the PCX2 Bilinear filtering is also used.

Unzip the files in the Tomb Raider directory and read the README.TXT
file.

PowerVR Tomb Raider Installation.  Version 1.06
===============================================
After unzipping the files in the 'C:\TOMBRAID' directory you will find
included two short cuts that are set-up already to run the PowerVR 
version of Tomb Raider. Just double click the short cut for your 
PowerVR board.

If any of the following apply to you then you should read over 
the additional install notes below.

- If you use a joystick with Tomb Raider
- If you do not have your CD configured in CONFIG.SYS and AUTOEXEC.BAT 
  to run under DOS.
- If you have not yet configured the audio with the Tomb Raider 
  SETUP.EXE program.
- If you have installed the Tomb Raider files to a directory other
  than 'C:\TOMBRAID'

PowerVR Tomb Raider Game Notes.    Version 1.06
===============================================
The following Keys perform the following operations.
F1       - Decreases the screen resolution.
F2       - Increases the screen resolution.
F3       - Displays the current resolution, frames per second and
           whether Single Buffered mode is on.
F4       - Toggles the PowerVR logo. (Full version only).
F8       - Toggles Singled Buffered mode. To switch mode
           the graphics will be reset to the starting resolution
           of 640x480. 
Z        - Zoom the camera in.
X        - Zoom the camera out.
All other keys operate as in the original game.

Single Buffered mode allows the use of high resolutions on 
a 2MB 2D graphics board and it will improve the average frame rate.
However as the 3D image is being sent to the screen at the same time
as the monitor is displaying the image you may be able to see a line across 
the screen from time to time. This is called 'Cut Line' and is normal in
a Single Buffered mode.

Note that the PowerVR version tries to keep as faithful as possible to 
lighting and shading of the original Tomb Raider game. Some areas, 
especially in later levels, are meant to be quite dark.

PowerVR Tomb Raider Install Notes. Version 1.06
===============================================
1. Running under windows.
The PowerVR version of Tomb Raider runs in DOS only - not in 
a "DOS box" within Windows95. You must either exit Windows95 (using 
the "Start" Menu, "Shutdown", and "Restart the computer in MS-DOS mode"), 
or alternatively, by not running Windows95 when the PC is started.
We recommend exiting Windows95 using a short cut such as the ones supplied. 
This is more convenient and makes the audio set-up easier. If you 
have not installed in the 'C:\TOMBRAID' directory then you should 
create short cuts similar to the ones supplied. Note that it is 
important to have your CD installed for operation under DOS. This 
will mean you should have entries for a CD driver in CONFIG.SYS and 
that you should be using MSCDEX in AUTOEXEC.BAT.

2. Test the software version first.
If the software version, TOMB.EXE, doesn't run then neither 
will the PowerVR version! If you have only downloaded the PowerVR Demo
version and you are having problems, download and check the software 
version operates correctly under DOS and not just in a "DOS Box".

3. Check the audio set-up.
If the audio is not correctly set up, then the movies will not 
play correctly. Please note that the set-up for the sound card may
be different depending on whether windows has been run or not. Check 
the settings with the Tomb Raider SETUP.EXE program.

4. PCX1/PCX2 support.
There are two Tomb Raider executables: TOMBPCX1.EXE for earlier 
PowerVR cards with the PCX1 chip (e.g. Apocalypse 3D,or NEC PC3D Engine) 
and TOMBPCX2.EXE for those with PCX2 (e.g. Apocalypse 3Dx or Apocalypse 5D).
Either program will inform the user if the wrong one has been run.

5. Using SciTech UNIVBE.
The PowerVR Tomb Raider uses the VESA 2.0 graphics card BIOS standard. 
Most modern cards come with this. However, for cards which do not, 
the game uses SciTech's UNIVBE technology to supply a VESA 2.0 BIOS. 
If the game detects a card which does not supply VESA 2.0, it will run
the UVCONFIG.EXE program which will create a suitable driver.
Although some graphics cards do supply VESA 2.O, they may not provide
very many resolution modes, or they may be causing a problem. You 
can override the card's BIOS and use SciTech's, by using the command 
line option UVBE.

6. Command line options.
The command line options should not normally be needed. They 
are case insensitive.
UVBE     - Forces the game to use SciTech's UNIVBE VESA 2.0 driver rather
           than the one supplied with the card (if any). This may also 
           increase the number of resolution modes available to the game.
INFO     - Prints out Program and Driver version numbers
16       - Forces the game to try to run even if the PC has less 
           than 16Mb of memory.
FIX1OSM  - If the display appears to be wrapping around, it could 
           indicate that incorrect information for the display
           has been supplied by the BIOS. This attempts to compute the
           information in a different way. Note that the 'O' in OSM is for
           'Off Screen Memory' and not a number Zero. 
JOY	 - Enables joystick control, however this is currently not compatible with
	   Cyrix CPUs.
Example: 
           C:\TOMBRAID> TOMBPCX2 UVBE

PowerVR Tomb Raider Known Issues.  Version 1.06
===============================================
1. Graphics cards with Tseng ET6000 and UVBE option.
The Tseng ET6000 should come with VESA 2.0 support on the board's 
BIOS so you should not have to use the UVBE option. However, if you do, 
on some systems using the UVBE option causes the program to hang. 
An interrupt clash is suspected.

2. Changing 2D Graphics Cards.
If the UVCONFIG.EXE has been used to create a VESA 2.0 driver for your
graphics card, then changing the graphics card may confuse the driver
software. If this appears to be the case, we suggest deleting 
UVCONFIG.DRV and UVCONFIG.DAT in the Tomb Raider directory. This will 
force the game to regenerate driver information.

3. Black Screen on Exit.
Some systems may not return you to a normal DOS prompt. You are still
in DOS - it is just the graphics mode has not been restored. To clear 
the screen type 'mode co80' and hit return.

4. Using saved games between the software and PowerVR versions.
Saved games between the PowerVR and software versions are not compatible.
You will not be able to load the games from the other version.

5. Joystick support does not work on some non-Pentium CPUs.
